the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, forming part of this specification.

My invention relates to a. spray apparatus used with bath tubs, and theprincipal objects of my invention are to provide a device of this classin which the spray-nozzle may be easily and quickly turned or adjustedin any desired position, and to maintain its position of adjustmentwithout the aid of the user or without external support, and to providea spray-nozzle which will project or throw a series of sprays vindirections different from each other, and

which may be directed to practically a common point, and further toprovide a simple means of detachably mounting the bathspray in operativeposition.

With these and other objects in view, my invention consists in thevarious novel and peculiar arrangements and combinations of diii'erentparts of the apparatus, all as hereinafter fully described and thenpointed out in the claims.

I have illustrated types of my invention in the accompanying drawings,wherein Figure 1 is a side view of a bath tub equipped with myimprovements, one endy of the tub being broken away to show the fixturewithin the tub. Fig. 2 is a sideview of the clamp for detachablymounting the bath-spray upon the faucet or fixture of the tub. Fie' 3 isanother view of the clamp for detachably securing the bath-spray inplace, the clamp being adjusted in a position at right angles to thatshown in Fig. 2. Figs. 4 and 5 are views of a modified form of the clampfor detachably securing the bath-spray in place upon the fixture, the

views of the clamp being taken at right an` gles to each other. Fig. 6is an lenlarged view of one of the spray-nozzles shown in` Fig. 1, thenozzle being here shown as turned on its axis through a half circle toinvert it, the dotted line position showing the nozzle as' adjusted in adownwardly pointing position. Fig.l 7 is a side view of a modlticationofthe bath-spray and shows -the nozzle supporting pipe,' which is offlexible metal, being made comparatively long and itself supportedby aclamp at its lower end, and the clamp being shown as attached to thevertical part of fa faucet. In this view the dotted lines show thespraynozzle in a different position of adjustment.

Fig. 8 is a side View of a modication of the pipe for supporting thespray-nozzle, the pipe here shown being a lflexible metal pipe havingsolid cylindrical walls as contradistinguished from the i corrugatedie-xible meta-l pipe shown in Fig. 7 In this View the dot-ted lines showthe spray-nozzle as moved into a different adjustment. Fig. 9 is anenlarged front View of my improved spray-nozzle shown as detached. Fig.10 is a horizontal sectional view of the spraynozzle shown inFig. 9, theplane of the view being indicated by line 10-10, Fig. 9. Fig. 11 is acentral vertical sectional view of the spray-nozzle shown in Fig. 9.Fig. 12 is a diagrammatic view'showing the respective lengths of a pairof arc-shaped nozzles when used together upon the same pipe,

Referring to the drawings in which like numbers of reference designatelike parts throughout, my improved spray-nozzle indicated by the numeral1 is shown as constructed of sheet metal and is of an elongated shapemade substantially in the form of an arc, and with the face thereofprovided with a plurality of groups of sprayholes 2, 3 and l. Thenozzles are hollow practically throughout, and the face thereof whichbears the groups of spray-holes is made in a peculiar form, as indicatedin the drawings, and so that each group of sprayholes or rose is in adifferent plane from that of the adjacent group or groups. For

example, assuming that the nozzle is set so that the plane containingthegroup of spray-holes 3, stands in a vertical plane, the

lplanes lcontaining the 'other two' groups 2 and 4, make an obtuseyangle with the said vertical plane, and lthe said planes contain-- ashereinafter described. The pu ose-of having the groups of spray-h oles tus arranged is to provide a plurality of spra s which comingv fromdiHerent points of t e elongated nozzle may converge and be thrownagainst practically a common polnt, thus reventing the sprayed waterfrom being t irown beyond the sides of the bath tub. The length of theare form of the nozzle ma be made longer or shorter, as desired, an theangles between the planes containing the difl'erent groups ofspray-holes may be varied to control in thedesired manner the directionof each spray' relative to the others, the face of the nozzle beingbowed.

The back of the `spray-nozzle is provided with a tubular part 5, whichits within the tubular end 6, of the nozzle-supporting pipe 8, the jointbetween the two parts 5 and 6, being a friction-joint for permitting theready coupling and uncoupling of the parts and enabling the operator torotate the nozzle on its support, thereby permitting him to adjust thearc-shaped nozzle at any angular position relative to its sup-port.`Thus it can be completely inverted vwhen desired, the

friction-joint of course being capable of holding the nozzle againstdislodgment by the force of the water, the inverted position of thenozzle being shown in Fig. 6.

The pipe 8 both supports the nozzle and supplies the water thereto andthis pipe is a flexible metal one and has such flexibility as not torequire external support to give it the necessary rigidity to retain itsposition of adjustment, so that it can be liexed or bent by hand intoany desired position in order to change the direction in which thesprays are thrown by the nozzle. This is an important feature of theinvention, and it is carried out by means of a flexible metal pipehaving the described capacity, and for this purpose I use either anordinary corrugated flexible metal pipe, which is found as a commodityupon the market, or I use a cylindrical metal pipe having solidnon-corrugated walls, and made of a suitable metal such as block-tin,which will permit of the pipe being readily flexed or bent by handwithout much force, but at the same time has the described rigidity,that is to say, it will retain itself in the adjusted position withoutexternal support, a non-corrugated pipe for the nozzle of the kinddescribed being sho-wn at 8b in Fig. 8.

In Figs. 1 to 6, inclusive, I show the iexible metal nozzle-supportingpipe 8, as connected with a rigid 'metal pipe 9, which is detacha-blymounted in a clamp V10, which -is clamped to an ordinary faucet 11, of abath-tub 12, the faucet 1l, being supplied in .the usual way with bothhot and cold water, one of the supply-pipes of the faucet beingindicated at 13. The rigid pipe 9, is provided n'ear its lower end witha tubular lateral extension 14 which has its Aoutside formed .witha'spiral rib 15, (see Fig. 5), and when the pipe 9, is mounted invertical position in the clamp,- a rubber tube 16, is coupled betweenthe nozzle of the faucet 11, and the ribbed extension 14, ofthe pipe 9,

so that when the faucet is opened water is.

supplied to the vertical pipe 9.y In Fig. 1 I show a pipe 9, as beingprovided with-a pair of my improved nozzles 1, each being at` tached toand supported by a flexible metal pipe 8, receiving the water from thepipe 9. This pipe 9, is provided with a cock 17, for cutting off theupper nozzle, and a similar cock 18, for cutting oif both nozzles whendesired. In using a pair` of nozzles arranged one above the other, Iprefer to make the lower nozzle longer than the upper one, as indicatedin the diagrammatic View in Fig. 13, in order to give a greater spreadto the spray, for the reason that the lower nozzle directs its sprayswell within the conlines of the tub .without liability of throwing thespray beyond the sides thereof.

In the arrangement shown in Figs. 1 to 6, inclusive, the length of theflexible metal pipe 8, for supporting the spray-nozzles and j supplyingwater thereto should be suiiicient to permit of such pipe being readilyflexed by lhand in any direction about the point of support of the pipe,so that the user can easily bend the pipe into whatever posil 4tion hemay-desire in order to control the direction in which the sprays arethrown by the nozzle. In Fig. 1 the flexible pipe 8, of the upper nozzleis shown as adjusted in a Y substantially horizontal position, so thatthe vsprays will be thrown in arc-form when Viewed from the side, and assubstantially indicated by the dotted lines, while` the iiexible pipe ofthe lower nozzle is bent downwardly so that the sprays from the lowernozzle are thrown more directly downdotted lines. In Fig. 6 the flexiblepipe 8, of the spray-nozzle is shown as bent upwardly, which positionmay be desired when the nozzle is mounted at a very low point. Thedotted line position in Fig. 6 shows the iiexible metal pipe as bentdownwardly substantially on the order of theA lower nozzlevpipe in Fig.1.

In Fig. 7 I show a construction in which the flexible metal pipe 8a, ismade of Sullicient length to take the place of the rigid pipe, shown inFigs. 1 to 6, inclusive. In this construction the flexible pipe' 8", `issecured directly to the clamp 10, which is attached-to the dependingvertical part of the faucet 11, and the lower end of the iiexible pipe'8a, is provided with a smooth coupling-piece 19, over which is slippedone end of the rubber tube 20, the other end of such lwardly into thetub, as indicated by the tube being slipped over the end of the faucet11, to connect the faucet with the flexible pipe, the rubber tube 20,being provided at each end with an enlarged couplingpiece 21. Theflexible pipe 8 may be twisted in any direction about its vertical axis,as shown in the drawings, and it may also be bent or flexed laterally inthe position desired, the dotted lines in Fig. 7 showing the pipe bentsomewhat upwardly with the nozzle directed downwardly. In order toprotect the hand of the user in manipulating the corrugated form offlexible pipe, I provide a hand-grip in the form of a sleeve 22, whichis made of a Asoft material such as felt or leather.

In Fig. 8 I show the same form of construction as in Fig. 7, with theexception that the flexible pipe 8b has a smooth exterior, instead of acorrugated one. As hereinabove stated, this pipe maybe made of block-tinor a metal having the same capacity of flexibility and rigidity.

, It will thus be seen that by virtue of having the supporting-pipe ofthe nozzle made of a flexible metal having at the same time a certaindegree of rigidity, as above pointed out, and having the spray-nozzle somounted uponsuch a pipe that the nozzle may be turned on its axis intoany adjustment thereon, I provide a device in which the spray-nozzlehas,'what,I may term, universal capacity of adjustment. One of theimportant advantages in using a flexible pipe on the order of thatdescribed is, that all movable joints are dispensed with, and I amfurther able to use ordinary flexible metal pipe as found upon-themarket.

The character of the flexible metal pipe which supports the spray-nozzleand permits of its universal adjustment is such as to readily admit ofbeing bent, bowed or twisted by hand without breaking or rupturing, andat the same time has sufficient rigidity to maintain its position ofadjustment without external support and without liability of being movedout of such adjustment by the pressure or fo-rce of the body of waterpassing through the pipe. This pipe may be repeatedly flexed and twistedwithout destroying it or incapacitating it in the performance of itsfunction of providing a secure conduit for the passage of water underpressure and of remaining in its adjusted position without the aid ofexternal support. j

The clamp 10, for detach'ablyy securing the rigid pipe 9, or the exiblepipe 8, to the faucet 11, is provided with two pipe-receiving sockets 22and 23 respectively, which are located at right angles to each other,the socket 23 in the end of the clamp'be'ing used to receive the pipewhen mounted upon the horizontal part of the faucet 11, as indicated inFigs. 1, 2 and 3, respectively, while the other socket 22, is used forholding the pipe whenthe clamp is mounted upon the vertical part of thefaucet 11, as indicated in Figs.v 3, 7 and 8.

The clamp shown in Figs. 1,2, 3,7 and 8, is composed of two similarmembers 24 and 25,

` the inner face of the respective members being formed with recesses 26and 27, respectively, which form a socket for receiving the part of thefaucet 11, on which the clamp is mounted. At another point on the innerfaces of the clampin members are recesses 28 and 29 for formmg thesocket 22, for holding thepipe, while atthe endofthe clamping membersthe 1 opposite inner faces of the kmembers arel recessedfat 30 and'31,respectively, to form the socket 23, for receiving the pipe. Theset-screws 32 and 33, are provided at each end of the clamping membersto bind them together, and a third set-screw 34, is arranged near ythecenter of length'of the members as an additional means for clamping themembers upon the faucet.

vIn Figs. 4 and 5 I show a modified form of the clamp and in which theclamp is composed of a single member, one end of which is formed with aring 36, into the sides' of which are let a series of set-screws 37,which point toward the center of the circle, and the inner ends of whichscrews engage the part of the faucet 11, on which the clamp is mounted.From one side of the annular part or ring 36 projects a boss in which isformed laterally a socket 38, and in the end of this boss is formedanother socket 39, running' at right angles to the socket 38, and thetwo sockets intersecting. A; setscrew 40, is let into the side of theboss so as' to coperate with either socket 38 or 3.9. When this clamp issecured to a vertical part of the faucet 11, as indicated in Fig. 4, thepipe 9, ofthe spray-device is inserted in the socket 38,' and'thevset-screw 40, holds it in the socket. When this clamp is mountedupon a horizontal part of the faucet 11, as shown in Fig. 5, the pipe 9,of the spraydevice is inserted in the end socket 39, and the set-screw40, is turned down against the pipe so as to securely hold it in thesocket.

In'the-operation of my improved spraydevice, it will be readilyunderstood that the user of the device may before turning the Water onset the nozzlev in adesired position to spray a particular part of hisbody, by turning the nozzle on its1 point of support or iexing thesupporting pipe, or both, and that after such adjustment of either orboth of these parts, it is unnecessary for the user to hold any part ofthe apparatus with his where the lower nozzle is much elongate as it canbe and' still directs its sprays Within the tub.l

Having thus described my' invention, what I claim and desire to secureby Letters Iatcnt is:

1. A bath-spray comprising a spray-nozzle and a pipe for supplyingWaterl thereto, the said spray-nozzle being elongated and ofconsiderable Width and having-its front face curved or bent to form itinto a series of substantially flat plane surfaces forming angleswitheach other and each flat surface being provided with a group ofspray-holes, thev said groups of spray-holes being adapted to pro]ecttheir sprays at angles to each other but in a converging direction toconfine the sprays within the'bath-tub, substan tially as ascribed.

2.v A bath-spray comprising a spray-noz zle and a pipe connected wlthsaid nozzle and supplying water thereto, the said spray- `nozzle beingelongated and provided with a series of spaced roups vof spray-holesdisposed substantial y in a vertical are form and each disposed insubstantially a differcnt plane from the others, substantially asdescribed. s

In testimony whereof I have hereunto set 30 my hand in the presence ofthe two subseribing Witnesses, l v
